This is purely an attempt of Netflix to avoid California's new salary transparency laws. No stew makes anywhere near that kind of salary. Not even their pilots! What Netflix likely did was take a salary range of their entire workforce to comply with the new law. A more typical avg corporte fa salary in the US is ~120k if you look at the NBAA salary surveys for large cabin jets.
The side effect of this sensational news is now you'll have a bunch of stews inflating their self worth when they're not even required to be onboard by regulation. Even flexjet knows this by titling their job as a "cabin server" to serve the guests and that is all.
